Optimizing microwave-radar imaging parameters

Abstract

We outline a method for simultaneous optimization of multiple imaging parameters for microwave-radar imaging. Arguably, the most important parameter to determine is the effective permittivity to use for image reconstruction. The accuracy and reliability of the final image depends strongly on the ability to accurately estimate the effective permittivity. We demonstrate that our method is capable of estimating the correct effective permittivity, thereby reconstructing reliable images, by applying it to data collected with the Tissue Sensing Adaptive Radar system being developed at the University of Calgary.
